Hey all, I have got a lot of info from the forum so i signed up, Im into the crypto market and not a complete newbie, but my tactics are not efficient been over 1 and a half years since i properly got into mining due to just having a lot of spare gaming PC's

I have a coinbase account, a few wallets, and some odd tactics, but i know my goal is not to save up for a lambo, but Moreso to have a good spare bit of cash to buy stuff online with as my working money is typically spent on bills but if i can use crypto to minimise that that would be a godsend

I have 2 specific "mining rigs " (ryzen 2600x and gt 1030, Makes a okay combo for low wattage 0.15000 mBTC and a whole PC for cheap) 2 gaming laptops for boosting my income when im in the house, (never on 24h, 8 at most) GTX 1080 in main rig and a few spare rigs that i dunno what im doing with yet.

I use my computers for a lot of multipurpose stuff anyway so i do get my money out the hardware alone if im not mining.

I just want to know what i should be doing if im looking at this "spare cash" scenario, I can go out and slap x2 1060s in the ryzen rigs but then thats me just paying that back on finance, Im not up to date with crypto trends and what i should be doing like i dunno if i should be using nicehash or a different miner for a specific coin.

If the goal was monetary, i know all my PC's will get roughly £18 a week at current rates but thats if everything i have is on 24h and i would only keep the 2 mining specific builds on for 24h, i would like to be on at about £30+ a week based on current rates. (about 5.015 GBP per BTC)

Just need to be pointed into some path directions, Thanks for reading.
